SUMMARY
`xrnadr --scale` makes panels and notifications only update once a second on
nouveau driver.
STEPS TO REPRODUCE
1. Use nouveau driver for Nvidia Card.
2. Hover over icons in panel
3. The panel only updates once every second.
OBSERVED RESULT
When using `xrandr --scale 1.25x1.25` or any value higher than one:
Panels and notification pop ups only update every one or two sends (basically
they are running at 1 or 0.5 fps)
This happens to the widgets in the panel, meaning if I click on network manager
icon the menu renders at a smoothly. This can also be more visible by the date
and time only updating once every 2 seconds. The same thing happens with
notifications.
EXPECTED RESULT
The panel should update immediately. Meaning if I click or hover over an item
it should react immediately. (highlight or open)
